Hi gang,

I was hoping you could get me started in the right direction. My wife has an iBook G4 which lately, while using a full battery, just turns off suddenly. There is no warning and it never does it when it's plugged in. The battery looks like it's almost fully charged - at least that's what the meter in the menu says, so I don't know what's going on.

Could you possibly give me some steps to go through to try and figure this out? Thanks so much for your help.

PS: The first step she wants to try is to get a new Intel MacBook, but I'd like to try a couple of other things first! LOL

I've fixed a few iBooks with a problem like this. It was a logic board problem, now I can't say for sure that's what your problem is, but it sounds eerily similar. Check out this webpage http://coreyarnold.org/ibook/?p=20 I actually reflowed the solder on the chip, but I've seen some mild success doing it with this method. Good luck! Your wife may get her wish....

i've been having this same problem, and my boyfriend has been having it with his old powerbook. right around 40%-35% battery left, our computers will just shut down with no warning. if you restart still on battery, they immediately shut down again. when it does restart plugged in, it says that the date and time were reset to a time before 2001. is this what was happening with yours?

the only thing that our computers have in common are the security updates...

does it completely shut off or does it go into sleep? does the white light near the latch release pulse when it goes off?

it completely shuts down. my bf keeps talking about a "random shutdown syndrome." i also noticed that now my battery drains A LOT faster. before this issue i would get almost 4 hours, now i'm lucky if i get 2. i'm going to take it in this weekend to see what my options are.

My Ibook just started doing this last week. I am still trying to figure out if its my battery or my logic board. The battery hasn't even done 200 cycles, so I am leaning towards the logic board. Anyone have better insight on whether this happens because of the battery or the logic board?

Logic board, folks. The iBooks are notorious for these.

Yep. I had one fail on me, brought it to the Apple Store, they brought it to the back room, put another one in, that one failed, and then finally found one that worked and replaced it.

About the battery life thing, mine has 411 cycles (8% health) with a 20 min battery life, and I noticed that originally when the battery ran out the computer would go into Sleep, but now it directly shuts down--no Sleep.

Since it is the logic board, and I have noticed, like the person above, that the shut down occurs at 35-40% and only when not connected to the charger. Is there any time-table on how long a logic board lasts once this shut down starts occurring?

Hey there - did you sort out the problem - I have EXACTLY the same issue - was it the logic board or the battery? Or is it power managment related? Thanks for any help...........RR:apple:

Sounds like your battery is bad. Get a new battery

Install coconut battery and check the condition of your battery
